Abstract
The utility model relates to an underground water depth keeping sampler. The sampler comprises a gravity hammer, a detention sleeve, a sampling tube, a piston connecting rod, an upper connector, an elastic clamp and a collar clamp, wherein the sampling tube is sleeved outside the piston connecting rod; the top of the piston connecting rod is provided with a sealing ring, is compactly matched with the inner wall of the sampling tube and can slide relative to the inner wall of the sampling tube; the bottom of the piston connecting rod is fixed on the gravity hammer through thread connection; the detention sleeve is fixedly locked on the gravity hammer; the upper connector is fixed on the sampling tube; the top of the upper connector is provided with a through hole; the lower end of the upper connector is provided with a water inlet which is communicated with the sampling tube; the collar clamp and the elastic clamp are respectively fixed on the sampling tube; and the elastic clamp is contracted to the inner wall of the detention sleeve through the collar clamp. The underground water depth keeping sampler has the outstanding advantages of reasonable and succinct design, convenient processing and low manufacturing cost. The sampler not only can be used for sampling and detecting in the process of disposing the sewage but also can be used for detecting the water quality of rivers and lakes.
Description
Technical field
The utility model relates to a kind of ground water fixed depth sampler.
Technical background
Underground water is subjected to the pollution of sanitary sewage, three industrial wastes, agricultural chemicals, chemical fertilizer, municipal refuse, buried tank leakage, ight soil and seawater etc., brings potential hazard for people ' s health and living environment, also is subject to people's attention day by day.
At present, underground water water sampling device has sampling pump, bucket sampler, directly water sampling etc. is descended in propelling in situ.These instruments have following shortcoming in use: when getting top layer or deep layer water sample, be difficult for control sampling flexibly, particularly on the bridge, on the limes marginis of dark sewage effluent, on the higher deck, accommodation, be difficult to bottle is reached the water surface, when perhaps needing to gather the deep layer water sample, the sampling jar position does not reach the degree of depth, has influenced the representativeness of sampling.In sewage sampling testing process, sampling appliance all adopts the plastics kettle, because the plastics kettle has only a upper shed, Hu Zui is little, not only to be used as water inlet and also will be used as exhausr port, during water sampling, need firmly kettle to be pressed in the water, cause sample time long, operating personnel are polluted, not only dangerous, but also unhygienic, in addition, when detecting chemical examination, Hu Zui is poured out sewage down, the water speed inequality is difficult to grasp the sample size that assay office needs, so whole sampling, detection chemical examination are brought very big inconvenience.
Summary of the invention
The utility model provides a kind of sampling fast, conveniently in order to overcome the defective of above-mentioned prior art, and operating personnel directly do not contact sewage, reduce sample time, chemically examine easy to detectly, safety and sanitation guarantee the underground depthkeeping water sampler of sample examination process safety and precise.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of ground water fixed depth sampler, comprise that gravity drop hammer, resistance are from cover, stopple coupon, piston rod, top connection, the outer stopple coupon that is socketed with of piston rod, the top of piston rod is provided with O-ring seal and closely cooperates and can slide relatively with the stopple coupon inwall, the bottom of piston rod is fixed on the gravity drop hammer by being threaded, resistance locks on the gravity drop hammer admittedly from cover, and top connection is fixed on the stopple coupon, and the top of top connection is provided with through hole, the lower end of top connection is provided with water inlet, and water inlet communicates with stopple coupon.Gravity drop hammer adopts stainless steel material.
The utility model also comprises elasticity folder and clip, in the stopple coupon periphery clip is installed, and the elasticity clamping fixes on the stopple coupon, and by clip the elasticity folder is reduced to resistance from the cover inwall.
Characteristics of the present utility model be convenient for carrying, easy to use, can gather the water sample of respective depth in strict accordance with national standard, make that to detect data accurate, all be suitable for for the water sample of gathering hydrostatic and circulating water.The utility model remarkable advantage is reasonable in design, succinct, easy to process, and cost of manufacture is low, not only can be used for sampling, detection in the sewage disposal process, also can be used for rivers, lake water quality detection.
Figure of description
Fig. 1, Fig. 2 are the utility model structural representation.
Embodiment
The utility model will be further described in conjunction with the accompanying drawings.
As Fig. 1, shown in Figure 2, the utility model comprises gravity drop hammer 1, resistance is from cover 2, stopple coupon 3, piston rod 4, top connection 5, elasticity folder 6 and clip 7, the outer stopple coupon 3 that is socketed with of piston rod 4, the top of piston rod 4 is provided with O-ring seal and closely cooperates and can slide relatively with stopple coupon 3 inwalls, the bottom of piston rod 4 is fixed on the gravity drop hammer 1 by being threaded, resistance locks on the gravity drop hammer 1 admittedly from cover 2, top connection 5 is fixed on the stopple coupon 3, the top of top connection 5 is provided with through hole, be the sampling rope on the through hole, the lower end of top connection 5 is provided with water inlet, and water inlet communicates with stopple coupon 3, in sampling, 3 peripheries are installed clip 7, and elasticity folder 6 is fixed on the stopple coupon 3, and by clip 7 elasticity folder 6 are reduced to resistance from cover 2 inwalls.Gravity drop hammer adopts stainless steel material.
The course of work: during use, the utility model is vertically put into water, make water inlet vertical with water (flow) direction, scale mark according to the sampling rope is determined the depth of water, and water inlet is aimed at water (flow) direction, pull-up sampling rope, the elasticity folder breaks away from resistance makes it separate with stopple coupon from cover, and at this moment, water inlet communicates with stopple coupon, under the effect of gravity, piston rod is to lower slider, and water sample flows to stopple coupon by water inlet, after waiting to have got water sample, propose sampler, water sample is gone in other water containers.
